  • Accessing Text Input Field Data

    - by 01010011
    Hi, Using CodeIgniter, how do I access and display text entered into an input field on a view file (see code below) from my controller file? // input_view.php $input_data = array('name' => 'search_field', 'size' => '70'); echo form_input($input_data);

  • PC to Macbook Pro Transition - Getting (re)started?

    - by Torus Linvald
    I'm in my second computer science course right now. I've enjoyed programming so far, but really have just scraped my way by. I've not done much programming outside of required class work. For similar reasons, I never really invested in downloading/learning software to help me program (IDE's, editors, compilers, etc). I know it sounds tedious, but my current setup is: notepad++ for coding; Filezilla to transfer .cpp & .h files to school's aludra/unix and compiling; unix tells me where my bugs are and I go back to notepad++ to debug; repeat until done. This isn't fun - and I know it could be easier. But I put it off knowing that I was soon going to switch to a Mac. And, tomorrow, I'm switching. So... How should I set up my Macbook for the best programming experience? What IDEs and editors and debuggers and so on should I download? How will Mac programming differ from PC? I'm open to all ideas and comments, even the most basic. (Background - I'm learning/programming in C++ right now. Next semester, my classes switch to Java. I'm also going to take a class in web development, with HTML/CSS/Javascript/PHP. My new laptop will be a late 2009 Macbook Pro with Leopard, or maybe Snow Leopard. Free would be preferrable for all programs.) Thank you all.

  • What's the best way to set cursor/caret position?

    - by Daniel Bachhuber
    If I'm inserting content into a textarea that TinyMCE has co-opted, what's the best way to set the position of the cursor/caret? I'm using tinyMCE.execCommand("mceInsertRawHTML", false, content); to insert the content, and I'd like set the cursor position to the end of the content. Both document.selection and myField.selectionStart won't work for this, and I feel as though this is going to be supported by TinyMCE (through something I can't find on their forum) or it's going to be a really ugly hack. Later: It gets better; I just figured out that, when you load TinyMCE in WordPress, it loads the entire editor in an embedded iframe. Later (2): I can use document.getElementById('content_ifr').contentDocument.getSelection(); to get the selection as a string, but not a Selection Object that I can use getRangeAt(0) on. Making progress little by little.

  • C++ union data-structure, easy acccess of bits within a DWORD

    - by TK
    Im running through a set of DirectX tutorials online and I have the following structure: struct CUSTOMVERTEX { FLOAT x, y, z, rhw; // from the D3DFVF_XYZRHW flag DWORD color; // from the D3DFVF_DIFFUSE flag } My basic understanding of directX leads me to thing tha color is made up of 8-bit alpha, red, green and blue channels. I am attempting to get east access to these channels. Rather than write the following code numerous times (within the CUSTOMVERTEX structure): public: int red() { return (color & 0x00FF0000) >> 16; } I could write a more elegant somution with a combination of a union and a structure e.g. struct CUSTOMVERTEX { FLOAT x, y, z, rhw; // from the D3DFVF_XYZRHW flag #pragma pack(2) union { DWORD color; // from the D3DFVF_DIFFUSE flag struct { char a; char r; char g; char b; }; }; } However this does not appear to function as expected, the values in r, g, & b almost appear the reverse of whats in color e.g. if color is 0x12345678 a = 0x78, r = 0x56. Is this an endieness issue? Also what other problems could I be expecting from this solution? e.g. overflow from the color members? I guess what Im asking is ... is there a better way to do this?!

  • Assign RegEx submatches to variables or map (C++/C)

    - by Michael
    I need to extract the SAME type of information (e.g. First name, Last Name, Telephone, ...), from numerous different text sources (each with a different format & different order of the variables of interest). I want a function that does the extraction based on a regular expression and returns the result as DESCRIPTIVE variables. In other words, instead of returning each match result as submatch[0], submatch[1], submatch[2], ..., have it do EITHER of the following: 1.) return std::map so that the submatches can be accessed via: submatch["first_name"], submatch["last_name"], submatch["telephone"] 2.) return a variables with the submatches so that the submatches can be accessed via: submatch_first_name, submatch_last_name, submatch_telephone I can write a wrapper class around boost::regex to do #1, but I was hoping there would be a built-in or a more elegant way to do this in C++/Boost/STL/C.

  • Updated Blue and Dark Visual Studio 2010 Themes

    I updated my previous dark theme for Visual Studio 2010 and added a new one with a blue background, similar to the background (but a bit lighter) to that of Visual Studio 2010s blue. I updated a few fonts to fit in with it and for the past week I have been using this and found that its even easier on my eyes than the dark theme. I made some changes to the dark theme, too, and include both of them in the download file here. My Blue Theme (click the images to see them larger)   My Dark...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Extreme Makeover, Phone Edition: Comcasts xfinity

    Mobile Makeover For many companies the first foray into Windows Phone 7 (WP7) may be in porting their existing mobile apps. It is tempting to simply transfer existing functionality, avoiding the additional design costs. Readdressing business needs and taking advantage of the WP7 platform can reduce cost and is essential to a successful re-launch. To better understand the advantage of new development lets examine a conceptual upgrade of Comcasts existing mobile app. Before Comcast has a great mobile app that provides several key features. The ability to browse the lineup using a guide, a client for Comcast email accounts, On Demand gallery, and much more. We will leverage these and build on them using some of the incredible WP7 features.   After With the proliferation of DVRs (Digital Video Recorders) and a variety of media devices (TV, PC, Mobile) content providers are challenged to find creative ways to build their brands. Every client touch point must provide both value added services as well as opportunities for marketing and up-sale; WP7 makes it easy to focus on those opportunities. The new app is an excellent vehicle for presenting Comcasts newly rebranded TV, Voice, and Internet services. These services now fly under the banner of xfinity and have been expanded to provide the best experience for Comcast customers. The Windows Phone 7 app will increase the surface area of this service revolution.   The home menu is simplified and highlights Comcasts Triple Play: Voice, TV, and Internet. The inbox has been replaced with a messages view, and message management is handled by a WP7 hub. The hub presents emails, tweets, and IMs from Comcast and other viewers the user follows on Twitter.  The popular view orders shows based on the users viewing history and current cable package. The first show Glee is both popular and participating in a conceptual co-marketing effort, so it receives prime positioning. The second spot goes to a hit show on a premium channel, in this example HBOs The Pacific, encouraging viewers to upgrade for this premium content. The remaining spots are ordered based on viewing history and popularity. Tapping the play button moves the user to the theatre where they can watch previews or full episodes streaming from Fancast. Tapping an extra presents the user with show details as well as interactive content that may be included as part of co-marketing efforts. Co-Marketing with Dynamic Content The success of Comcasts services are tied to the success of the networks and shows it purveys, making co-marketing efforts essential. In this concept FOX is co-marketing its popular show Glee. A customized panorama is updated with the latest gleeks tweets, streaming HD episodes, and extras featuring photos and video of the cast. If WP7 apps can be dynamically extended with web hosted .xap files, including sandboxed partner experiences would enable interactive features such as the Gleek Peek, in which a viewer can select a character from a panorama to view the actors profile. This dynamic inline experience has a tailored appeal to aspiring creatives and is technically possible with Windows Phone 7.   Summary The conceptual Comcast mobile app for Windows Phone 7 highlights just a few of the incredible experiences and business opportunities that can be unlocked with this latest mobile solution. It is critical that organizations recognize and take full advantage of these new capabilities. Simply porting existing mobile applications does not leverage these powerful tools; re-examining existing applications and upgrading them to Windows Phone 7 will prove essential to the continued growth and success of your brand.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Set defualt open with app to a python program on a Mac

    - by Vincent
    I use the open source application Ulipad http://code.google.com/p/ulipad/ do edit restructured text files (rst). It is a python application that I launch via terminal like so python32 UliPad.py I have python32 as an alias to the 32bit install of python on my machine. I have several versions installed. First I would like a way to launch ulipad like other osx apps. Not really sure how to do this. I would like to set all .rst files to be opened with UliPad.py. Is there a way to do this? I know how to choose the default app in finder but not sure how to choose ulipad as that app.

  • Bash script to replace spaces in file names

    - by armandino
    Can anyone recommend a safe solution to recursively replace spaces with underscores in file and directory names starting from a given root directory? For example, $ tree . |-- a dir | `-- file with spaces.txt `-- b dir |-- another file with spaces.txt `-- yet another file with spaces.pdf becomes $ tree . |-- a_dir | `-- file_with_spaces.txt `-- b_dir |-- another_file_with_spaces.txt `-- yet_another_file_with_spaces.pdf

  • groovy variable function

    - by bsreekanth
    I'm not even sure about how to title this qn. But, hope there is an easy way to do it in dynamic language like groovy. say I have a class Service, where I delegate the business logic. the methods in it are funA(), funB()... funX(). Now I have a controller class, where I call the service closure, which can be invoked like service.funA() . Now based on a variable (which can have values A, B ... X), I need to cal the correct service closure. Basically to avoid writing lot of if conditional statements. Something like service."fun+var"() would do. I'm not sure whether it is possible to substitute variable in closure (function)name. or any way by passing function (name) as a parameter...not sure I think PHP has a similar feature http://php.net/manual/en/functions.variable-functions.php thanks for any pointer..

  • How would you write a program to find the shortest pangram in a list of words?

    - by jonathanasdf
    Given a list of words which contains the letters a-z at least once, how would you write a program to find the shortest pangram counted by number of characters (not counting spaces) as a combination of the words? Since I am not sure whether short answers exist, this is not code golf, but rather just a discussion of how you would approach this. However, if you think you can manage to write a short program that would do this, then go ahead, and this might turn into code golf :)

  • Using Selenium IDE with random values

    - by Toby Hede
    Is it possible to create Selenium tests using the Firefox plugin that use randomly generated values to help do regression tests? The full story: I would like to help my clients do acceptance testing by providing them with a suite of tests that use some smarts to create random (or at least pseudo-random) values for the database. One of the issues with my Selenium IDE tests at the moment is that they have predefined values - which makes some types of testing problematic.

  • Is there a way to determine if a <select> dropdown menu is open?

    - by Robert
    I'm looking for a way to determine if/when a <select> element's menu is open. I don't need to force it to open or close, just figure out if it's open or closed at a given time. I can listen to events for focus/blur, mouseup/mousedown, etc., but I don't think I can reliably figure out the state of the menu from those events. For example, mousedown followed by mouseup could mean the user clicked and dragged to a selection and released (in which case the menu is now closed) or clicked and released to open the menu (in which case the menu is open). It also seems likely that the specific behavior of dropdown menus is browser-dependent. I know I could do this if I roll my own dropdown menu, but I prefer to use <select>. Is there a reliable way to find out if a dropdown menu is open? Or is this something that Javascript can't know?

  • Visual Studio Macros on 64 bit fail with COM error

    - by bruce.kinchin
    I'm doing some javascript development and found a cool macro to region my code ("Using #region Directive With JavaScript Files in Visual Studio"). I used this on my 32 bit box, and it worked first time. (Visual Studio 2008 SP1, Win7) For easy of reference the macro is: Option Strict Off Option Explicit Off Imports System Imports EnvDTE Imports EnvDTE80 Imports System.Diagnostics Imports System.Collections Public Module JsMacros Sub OutlineRegions() Dim selection As EnvDTE.TextSelection = DTE.ActiveDocument.Selection Const REGION_START As String = "//#region" Const REGION_END As String = "//#endregion" DTE.ExecuteCommand("Edit.StopOutlining") selection.SelectAll() Dim text As String = selection.Text selection.StartOfDocument(True) Dim startIndex As Integer Dim endIndex As Integer Dim lastIndex As Integer = 0 Dim startRegions As Stack = New Stack() Do startIndex = text.IndexOf(REGION_START, lastIndex) endIndex = text.IndexOf(REGION_END, lastIndex) If startIndex = -1 AndAlso endIndex = -1 Then Exit Do End If If startIndex <> -1 AndAlso startIndex < endIndex Then startRegions.Push(startIndex) lastIndex = startIndex + 1 Else ' Outline region ... selection.MoveToLineAndOffset(CalcLineNumber(text, CInt(startRegions.Pop())), text.Length) selection.MoveToLineAndOffset(CalcLineNumber(text, endIndex) + 1, 1, True) selection.OutlineSection() lastIndex = endIndex + 1 End If Loop selection.StartOfDocument() End Sub Private Function CalcLineNumber(ByVal text As String, ByVal index As Integer) Dim lineNumber As Integer = 1 Dim i As Integer = 0 While i < index If text.Chars(i) = vbCr Then lineNumber += 1 i += 1 End If i += 1 End While Return lineNumber End Function End Module I then tried to use the same macro on two separate 64 bit machines (Win7 x64), identical other than the 64 bit OS version and it fails to work. Stepping through it with the Visual Studio Macros IDE, it fails the first time on the DTE.ExecuteCommand("Edit.StopOutlining") line with a COM error (Error HRESULT E_FAIL has been returned from a call to a COM component). If I attempt to run it a second time, I can run it from the Macro Editor with no issue, but not from within Visual Studio with the macro explorer 'run macro' command. I have reviewed the following articles without finding anything helpful: Stackoverflow: Visual Studio 2008 macro only works from the Macro IDE, not the Macro Explorer Recorded macro does not run; Failing on DTE.ExecuteCommand Am I missing something dumb?

  • HTML Scraping in Php.

    - by tsellon
    I've been doing some html scraping in PHP using regular expressions. This works, but the result is finicky and fragile. Has anyone used any packages that provide a more robust solution? A config driven solution would be ideal, but I'm not picky.

  • Getting Started: Silverlight 4 Business Application

    - by Eric J.
    With the arrival of VS 2010 and Silverlight 4, I decided it's time to look into Silverlight and understand how to build a 3-Tier business application. After several hours of searching for and reading documentation and tutorials, I'm thoroughly confused (and that doesn't happen easily). Here are some specific points I don't understand. I welcome guidance on any of them, and also would appreciate any references to a really good tutorial. Brad Abrahm's What is a .NET RIA services (written for Silverlight 3) seemed very promising, until I realized I don't have System.Web.Ria.dll on my system. Am I missing an optional download? Was this rolled into another DLL for Silverlight 4? Did this go away in favor of something else in Silverlight 4? This recent blog says to start from a Silverlight Business Application, remove unwanted stuff, create a WCF RIA services Class Library project, and copy files and references from the Business Application to the WCF RIA services project, while manually updating resource references (perhaps bug in B2 compiler). Is this really the right road to go down? It seems very clumsy. My requirements are to perform very simple CRUD on straightforward business objects. I'm looking forward to suggestions on how to do that the Silverlight 4 way.

  • File::GlobMapper doesnt seem to be exporting globmap

    - by justintime
    The following is pretty well copied from the documentation. use File::GlobMapper qw( globmap ); for my $pair (globmap '<*.tar.gz>' => '<#1.tgz>' ) { } And it gives String found where operator expected at globmapper_test1.pl line 4, near "globmap '<*.tar.gz>'" (Do you need to predeclare globmap?) (Using ActivePerl 5.10.0 on Windows) Side questions - if GlobMapper only exports one function, why is it set so you have to export it explicitly?
